Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; State of North Carolina

Özet

On April 27, 1994, the North Carolina Department of Environmental Management (NCDEM), submitted a maintenance plan and a request to redesignate the Winston-Salem/Forsyth County area from nonattainment to attainment for carbon monoxide (CO). The CO nonattainment area consists only of Forsyth County. Under the Clean Air Act as amended in 1990 (CAA), designations can be revised if sufficient data is available to warrant such revisions. In this action, EPA is approving the North Carolina request because it meets the maintenance plan and redesignation requirements set forth in the CAA.
